Is this specific to levm? It doesn't seem that way?

This change is specific to LEVM because withdrawal processing was working right with REVM.
The main difference is that LEVM implementation doesn't update the db, it just computes AccountUpdates and after the whole execution we update the database outside of execute_block(). I still have to see what we want the execute_block function to do, my goal was to return AccountUpdates alongside Receipts and after that update the state.
This is a quick fix for the hive tests but I think that I'll have to make some changes to the add_block and execute_block functions so that we can use them indistinctively.

LGTM, left you some comments:

[maximopalopoli]

Can we specify the type when declaring balance_increments to avoid using ::<Vec<_>>? Or do you think the current way of doing it is better?

[maximopalopoli]

Also in my opinion it would be good to avoid "as" conversions, and use from, or try_from if necessary.
